i have a 96 873. my auxillary hydraulics will work when moving side switch left or right.will not lock in with trigger . had bobcat tech come and check it out and was told it was the switch. $600.00 later no luck. when press buttons for aux both green lights come on .does not give any flashing lights according to manual everything should be good. would like some suggestions as it is to hard to run a cold planer with side switch. thanks
